WINDLASS.

SPECIFICATION forming part of Letters Patent No. 282,075, dated July 31, i883.

i Application filed March 5, 1883. l(No model.)

.To aZZ whom it may concern:

Be it known that I, CYRUs J. HALL, of Belfast, in the `county of Valdo, of the State of Maine, have invented a new and useful Improvement in Windlasses for Navigable Vessels; and I do hereby declare the same to be described in the following specication/and represented in the accompanying drawings, of which- Figure 1 is a front elevation, Fig. 2 a longitudinal section, and Fig. 3 a transverse section, of a windlass embodying my invention, the nature of which is defined in the claim hereinafter presented.

In the said drawings, A denotes the shaft of the windlass, it being duly journaled in boxes c a a, supported by bits B C B, arranged as represented. rIhis shaft, at each end of it, is provided, as usual in other windlasses, with a barrel, D, and, besides, near its middle, it has fixed upon it concentrically two ratchetwheels, E E, each being provided with an op erative pawl-case, F, suitably furnished with pawls or teeth to engage with the ratchet- Each pawl-case is jointed to the lower part of a lifter-rod, G, such rod being provided at its upper end with a handle, @from the shank of which a tooth, c, extends and rests in one of a series of notches, d, of a rocker-lever, H, pivoted to a standard, I, erected on the deck K, and directly over the middle of the windlass. This rocker-lever is socketed at each end to receive a brake, L, for

brake or strap for regulating its revolutions when an anchor-chain carried by the said wheel may beV running out.

Each sprocket-wheel is suitably made to engage with a clutch, N, arranged to slide onthe shaft lengthwise thereof, and adapted thereto by what is termed a .feather-connection,7 so as to cause it to revolve with, and be revolved by, the shaft.

Each of the two clutches N is grooved circumferentially to receive two clasps or lugs, f f, projecting from one side of ahand-wheel, O,

i. that screws upon the shaft, which, for a suflicient distance, is screw-threaded to receive and engage with the hand-wheels. On revolving either hand-wheel itwill be caused to move on the shaft lengthwise thereof, such being to enable the clutch of such wheel to be moved either into or out of engagement with the next adjacent of the two sprocketwheels.

By means of the handle b of the lifter-rod G a person can readily shift the tooth c into either of the notches d of the next adjacent arm of the rocker-lever H, as occasion may require.

In practice a windlass constructed as described has been found to be very efficient or to operate to excellent advantage.

In the windlass, the combination ofthe rocker-lever provided with the two series of notches in its arms, and the pawl-case lifter-rods having teeth to enter such notches, with the pawl-cases, ratchet and sprocket wheels, screw-threaded shaft, hand-wheels, and clutches, all being arranged and adapted substantially as shown and described.
